[jboss-jira] [JBoss JIRA] Commented: (JBRULES-505) Using a GLOBAL value in predicates in more than one rule - rule fails to evaluate correctly.

Using a GLOBAL value in predicates in more than one rule - rule fails to evaluate correctly. -------------------------------------------------------------------------------------------- Key: JBRULES-505 URL: http://jira.jboss.com/jira/browse/JBRULES-505 Project: JBoss Rules Issue Type: Bug Security Level: Public(Everyone can see) Components: All Affects Versions: 3.0.4 Environment: Windows XP, JBoss 4.0.3SP1, JRules3.0.4, PackageBuilderConfiguration.JANINO Reporter: Matt Green Assigned To: Mark Proctor SAMPLE CODE: =============================================== package net.rockshore.rmf.rules #list any import classes here. import net.rockshore.rmf.entities.SubscriptionLocal; import net.rockshore.rmf.entities.EventLocal; import java.lang.String; #declare any global variables here global java.util.Collection resultsCollection; global java.lang.String eventType; rule "KeepSubscriptionsToEventType" when subscription : SubscriptionLocal (eventTypeDiscriminator == (eventType)) then resultsCollection.add(subscription); System.out.println("Keeping Subscription:" + subscription + " is of type:" + eventType); end rule "DiscardSubscriptionsToWrongEventType" when wrongSubscription : SubscriptionLocal (eventTypeDiscriminator != (eventType)) then System.out.println("Discarding Subscription:" + wrongSubscription + " NOT of type:" + eventType); retract (wrongSubscription); end =============================================== TEST DATA SET: ------------------------- SubscriptionLocal objects asserted KEY, EVENTTYPEDISCRIMINATOR --------------------------------------------------------------------------------------------------------- 5c4o12-mexdpy-esmukytr-1-esmx439o-58 , net.rockshore.rmf.entities.events.business.TravelAlertEvent 5c4o12-mexdpy-esmukytr-1-esmx438t-57 , net.rockshore.rmf.entities.events.business.FlightDelayEvent 5c4o12-mexdpy-esmukytr-1-esmx438t-56 , net.rockshore.rmf.entities.events.business.FlightDelayEvent GLOBAL variable eventType = "net.rockshore.rmf.entities.events.business.FlightDelayEvent" PROBLEM DESCRIPTION: ------------------------------------- When firing the above rules with data shown above, the result shows that "DiscardSubscriptionsToWrongEventType" rule was fired for Subscriptions with keys ending 57 and 56. This is the wrong way round as that rule should have fired only with Subscription 58. Further, rule "KeepSubscriptionsToEventType" did not fire. FURTHER ANALYSIS: ------------------------------- If one rule OR the other is deleted then the remaining rule fires correctly. If both rules have the predicate replaced with a String literal "net.rockshore.rmf.entities.events.business.FlightDelayEvent" then both rules fire correctly. The problem still occurs when eventType predicate is replaced with eventType.toString()
